Any open source project may choose to purchase a commercial subscription to enable additional privacy features. Proprietary projects require a commercial subscription. Details about commercial subscriptions are found on the project's "Sharing" page.

Project's with a commercial subscription can configure the bug and branch sharing policies:

• Public
  Branches or bugs are public unless they contain sensitive information.

• Public, can be proprietary
  New branches or bugs are public, but can be made proprietary later.

• Proprietary, can be public
  New branches or bugs are proprietary, but can be made public later. Only people who can see the project's proprietary information can create new branches or bugs.

• Proprietary
  Branches or bugs are always proprietary. Only people who can see the project's proprietary information can create new branches.

We recommend that projects share all information types with their developer teams. Sharing with your organisation team will also ensure your co-workers are informed and can do their job. Avoid sharing with users because they leave projects and organisations; if a user needs access to confidential information either add the user a team that is already shared with or subscribe the user to just the bugs and branches then need to work with.

As the maintainer of a project with a commercial subscription, you can create:

• private teams
  Visible team members only

• Private mailing lists
  Visible to team members only

• Private package archives
  Visible to team members and to users you offer a package subscription too

You can purchase a commercial subscription at the Canonical store Commercial subscriptions cost US$250/year/project + applicable V.A.T. If you select 'Other/Proprietary' as the project license, the project overview page also shows the directions to purchase a commercial use subscription
